Motoneurone pool and the H-reflex.

Potentiation of `late' responses evoked in muscles during effort

“…EXCITED REFLEXLY Taborikova and Sax (1968) describe two methods for estimating the fraction of the motoneurone pool contributing to an H-reflex. One of their methods, depending on the refr-ct ry periods of axons, is not applicable to the experimental situation in the present study where motor axons are conducting volitional, as well as reflex, impulses.…”

Daily muscle vibration amelioration of neural impairments of the soleus muscle during 2weeks of immobilization

“…Maximal H-wave amplitude (Hmax) compared with maximal muscle compound action potential (M-wave) has been generally used to assess the excitability of spinal motoneurones (Funase et al, 1996;Taborikova and Sax, 1968). Many investigations have examined Hreflex activity following unloading interventions in humans and have reported either significant increases (Clark et al, 2006a;Duchateau, 1995;Lundbye-Jensen and Nielsen, 2008a,b) or no changes (Kaneko et al, 2003;Lambertz et al, 2003).…”

Changes of Electrically Elicited Reflexes in Hand and Forearm Muscles in Man

“…Patient studies have shown that patients suffering from an upper motoneuron disease or motor cortex lesion have a very small amplitude or even abolished LL response (6,7). The short-latency, monosynaptic spinal reflex can also be examined by the H-reflex method (8)(9)(10). Generally the H-reflex is known to occur in the lower limb (soleus or gastrocnemius muscles (8)(9)(10)).…”

“…The short-latency, monosynaptic spinal reflex can also be examined by the H-reflex method (8)(9)(10). Generally the H-reflex is known to occur in the lower limb (soleus or gastrocnemius muscles (8)(9)(10)). However, it has recently been elicited successfully in the forearm of adult humans (11,12).…”
